Xperia has a simple interface in the current interface. It was not too many fancy 3D effects as in Sense, did not have too many features like the TouchWiz. Xperia users can get familiar with this interface in less than a half day. Every nook and cranny will be "discovered" all. But there are some features that you do not need to. Then you can decide to "eliminate" it to operate smoothly!
